Abstract

Eljárás (III)-(2R,3R) általános képletű treo-(2R,3R)-2-hidroxi-3-(2-aminofeniltio)-3-(4-metoxifenil)-propionsav-származékok átalakítására,ahol R1 jelentése egyenes vagy elágazó szénláncú 1-3 szénatomosalkilcsoport vagy hidrogénatom, III-(2R,3R) és III-(2S,3S)enantiomerek keverékévé, amelyet úgy végeznek, hogy (a) a III-(2R,3R)általános képletű vegyületet gyűrűzárással a megfelelő (IV)-(2R,3R)képletű vegyületté alakítják, (b) a kapott vegyületet (V) általánosképletű vegyületté alakítják, ahol R2 jelentése hidrogénatom vagy 2-4szénatomos acilcsoport, (c) a kapott vegyületet redukálva (IV)-ciszképletű vegyületté alakítják, majd (d) a gyűrűt erős savval vagy erősbázissal alkoholos vagy vizes oldószerben felnyitják. Az eljárás révéna diltiazem szintézisben keletkező III-(2R, 3R) általános képletűvegyület hasznosítható. Ó
